Svet_ta [14]

Answer:

The new version contains 15 lemons, 6 cups of water and 6 tablespoons of honey

Step-by-step explanation:

The given ingredients used to make the lemonade are;

The number of lemons = 5

The number of cups of water = 2

The number of tablespoons of honey = 2

Therefore a new version the lemonade recipe that would make more lemonade but that would still taste the same as the lemonade made with the given recipe is found by scaling up the quantities of the ingredients in the given recipe as follows;

The ingredients used to make the new lemonade are obtained by multiplying the ingredients in the given recipe by a factor larger than 1;

The number of lemons in the new recipe = 5 × 3 = 15

The number of cups of water in the new recipe = 2 × 3 = 6

The number of tablespoons of honey in the new recipe = 2 × 3 = 6

Alina [70]

Answer:

Amount of water left in tank = 440 cm³

Step-by-step explanation:

Given:

Sides of tank respectively = 35 cm , 28 cm , 16 cm

Water level in tank = 2/5

Side of a cubic tank = 18 cm

Find:

Amount of water left in tank

Computation:

Volume level in rectangular tank = [2/5][35 x 28 x 16]

Volume level in rectangular tank = [2/5][15,680]

Volume level in rectangular tank = [31,360/5]

Volume level in rectangular tank = 6,272 cm³

Volume of cube = side³

Volume of cube = 18³

Volume of cube = 5,832 cm³

Amount of water left in tank = Volume level in rectangular tank - Volume of cube

Amount of water left in tank = 6,272 - 5,832

Amount of water left in tank = 440 cm³
